InheritableOptions provides a constructor to build an OrderedOptions hash inherited from another hash.

Use this if you already have some hash and you want to create a new one based on it.

h = ActiveSupport::InheritableOptions.new({ girl: 'Mary', boy: 'John' })
h.girl # => 'Mary'
h.boy  # => 'John'
